realm = plugin>codehaus.mojo:sonar-maven-plugin:3.7.0.1746

Question

我根据github sonar-custom-rules-examples/java-custom-rules/上的说明编写了Java自定义扫描规则。我的java自定义规则已成功添加到SonarQube中，但在扫描代码工程时代，出现了以下错误。有没有人可以帮我解决下面的错误。

任何解决问题的提示都是非常受欢迎的！

谢谢!

Answer 1

虽然不清楚为什么会发生这种情况，但我用另一种方式绕过了这个错误。这是之前的代码所写的：

JavaSymbol.VariableJavaSymbol variableJavaSymbol = (JavaSymbol.VariableJavaSymbol) identifierTree.symbol();
VariableTree variableTree = variableJavaSymbol.declaration();

为避免错误，未使用JavaSymbol.VariableJavaSymbol。

VariableTree variableTree = (VariableTree) identifierTree.symbol().declaration();
